This is an artificial data set, cleverly construced and used by
Antille and May to demonstrate ‘problems’ with LMS and LTS.
A data frame with 12 observations on 2 variables,
Because the points are not in general position, both LMS and LTS

Antille, G. and El May, H. (1992)
The use of slices in the LMS and the method of density slices:
